Title: Auxiliary lubrication device
IPC: F01D25/20
Filed: 1961-10-24
Abstract: 955,863. Lubricating. H. EBERSPACHER, and W. EBERSPACHER, [trading as J. EBERSPACHER]. Oct. 24, 1961 [Dec. 8, 1960], No. 38085/61. Heading F2A. An auxiliary lubricating device for an exhaust-operated super-charger of an internal combustion engine is located in a lubrication supply line between the engine and the bearings 3, 4 of the super-charger 1 and comprises a reservoir 6 which connects oil delivery pipe 5 from the engine and pipe 5a to the supercharger bearings 3, 4. Within the reservoir is located a bellows 8 to the base plate of which is connected a piston-rod 9 which at its free end carries a spring 11. In normal operation, oil under pressure from the engine is fed through pipe 5 and non-return valve 7, through reservoir 6 and pipe 5a to the bearings 3, 4. To ensure an adequate and immediate supply of oil when starting, prior to the normal pressure build-up in the system, oil may be supplied from the reservoir 6 by the bellows 8 by pressure from the spring 11 acting on the pistonrod 9. This operation is permitted by the release of a spring-loaded stop 12 by an electromagnet 13 connected to the starter circuit of the engine. Oil displaced under the spring pressure on the bellows closes the non-return valve 7 and is fed direct to the bearings 3, 4. via pipe 5a. The rate of displacement is controlled by a brake nozzle 10 which controls the inflow of air to the remote side of the bellows. The spring pressure of the device is lower than the normal pressure in the system such that when said normal pressure is reached the valve 7 opens and the bellows are returned to their initial position and locked by the stop 12, the reservoir being subsequently replenished. Another embodiment incorporates a solenoid type electric pump in place of the spring actuated means described and which is formed as part of the reservoir and electrically connected with the engine starting means.
